Metallics BHDM18 – Frequently Asked Questions
1) What size hole does the Metallics BHDM18 bell hanger bit drill, and how deep can it go?
The BHDM18 is a 3/4 inch diameter bell hanger bit with a 13 inch overall length, so it will bore a 3/4 inch hole through framing, sill plates, and masonry walls up to roughly the depth the shank allows once the chuck and bit holder are accounted for. The 3/4 inch bore is the common size for pulling low voltage, alarm, or communication cable through a wall.
2) What is the fish hole on a bell hanger drill bit used for?
The fish hole near the tip of the BHDM18 lets you thread wire or a pull string through the bit itself. You drill the hole, feed the cable through the fish hole from the far side, then back the bit out and the wire comes with it. That is why security installers and alarm techs reach for a bell hanger bit instead of a standard auger when running cable through a wall they can only access from one side.
3) Will a carbide tipped bell hanger bit go through masonry and brick, or just wood?
The BHDM18 is carbide tipped, so it handles wood framing plus brick, block, and mortar, which is what you hit on an exterior wall penetration for a service entry or camera run. A plain high speed steel bell hanger bit will dull fast on masonry; the carbide tip is the reason to pick this one for mixed wall construction.
4) Is 13 inches long enough to get through a wall with a plate and sheathing?
A 13 inch bell hanger bit is sized for single plate and standard stud wall penetrations. Drilling down through a 2x top plate from an attic, or sideways through a 2x4 or 2x6 wall with sheathing, is well inside its reach. Double top plates with a thick exterior assembly, or a deep masonry wall, can run past what a 13 inch bit will clear, and in that case you want a longer bell hanger bit or a bit extension.
5) Is the Metallics BHDM18 sold individually or in a multi pack?
One bit per order. The BHDM18 ships as a single piece in a pouch, so if you are stocking a van or kitting multiple crews you order the quantity you need rather than a box.
6) What is the exact part number to order the 3/4 inch Metallics bell hanger bit?
Order Metallics BHDM18. That is the manufacturer part number for the 3/4 inch diameter, 13 inch carbide tipped bell hanger bit with the fish hole.
